Example:

    Source (English):

        «««
        Create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}
        »»»

    Wrong translation (German) – Anchor added to the URL.

        «««
        Erstelle eine [virtuelle Umgebung](../virtual-environments.md#create-a-virtual-environment){.internal-link target=_blank}
        »»»

## Installation { #installation }

Erstellen und aktivieren Sie eine <a href="https://fastapi.tiangolo.com/de/virtual-environments/" class="external-link" target="_blank">virtuelle Umgebung</a> und installieren Sie dann FastAPI:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>
